Thanks for the info.., looks like I will probably end up with either a hitech or eflight receiver, and respective servos. I currently have an Airtronics RD6000 radio. Do you see any problems using this transmitter with either the hitech or eflight receivers? Can I take a crystal from one of my existing airtronics receivers and use it in the other receivers, or just purchase that receivers crystal for my channel number, or would it matter? thanks again.
